I have questions about CCleaner's System Restore tool.
First, some background.
Reading about it here:
http://docs.piriform.com/ccleaner/using-cc...-restore-points
I noted this:
"Note: CCleaner removes references to the System Restore points, but may not actually remove all files related to each point."
I know Windows System Restore takes HDD space until it gets to some predefined percentage. Above this percentage, older Restore Points are deleted automatically while creating the new ones.
So, the reason to use CCleaner's System Restore tool is to temporarily gain some HDD free space.
Additional info:
Windows Vista Home Basic 32 bits x86.
CCleaner portable 2.22.968.
Windows User with administrative rights, and running everything with "Run As Administrator" option.
UAC enabled.
My system is working ok.
So now, about my questions.
------
Maybe someone could explain about my first question/issue:
A_ What is the meaning of removing "references"? If all related files are still there (according to the above note), but the Restore Point is already deleted, what can Windows do with those files? Does these "leftover" files are just talking free space from the HDD, or there are useful or essential to Windows?
------
The second question/issue is:
B_ If I disable Windows System Restore at all, are those "leftover" files indeed deleted by windows? Or in this case will those files still be there?
------
The last issue is about the relation between CCleaner's System Restore tool, and Windows Device Manager.
Using devmgr_show_nonpresent_devices environment variable, I displayed old devices in Windows Device Manager. By showing also hidden devices, I displayed old "Generic volume shadow copy" (grayed) items. I managed to delete those items, leaving only the active (not grayed) shadow copies.
Then, I realized that when I delete Restore Points using CCleaner's System Restore tool, then Windows Device Manager shows them as old (grayed) "Generic volume shadow copy" items.
Of couse, when I deleted those Restore Points using CCleaner, I knew 100% that I will not need them.
So, the third question/issue is:
C_ Is it safe to delete those old items in Windows Device Manager? What's the relation in this case between those "leftovers" files and the deleted items in Windows Device Manager?
------
I just want to understand all this about System Restore so to use it the best way I can.
Thank you in advance.
